Definitions

• the present invention relates to highly water-soluble dyestuff preparations for the dyeing or printing of natural and synthetic poly-amide fibre materials, having a content of 10 to 99 parts by weight of at least one dyestuff of the general formula ##STR2##
• WHEREIN X represents a hydroxy, methyl, ethyl, methoxy or ethoxy group
• Y represents a hydrogen atom or the methyl group, 0.5 to 90 parts by weight, preferably 0.5 to 15 percent by weight of a higher molecular organic auxiliary of the series of polyglycols having an average molecular weight of 3000 to 20 000, polyglycol ethers of fatty alcohols or fatty acid amides containing hydroxyl groups with 8 to 20 carbon atoms having 15 to 30 ether groups, alkylbenzene-phenyl-ether disulfonates (alkyl C 1 - C 6 ), dialkylnaphthalene-sulfonates (alkyl C 1 - C 6 )
• the above-mentioned higher molecular organic auxiliaries which cause an increased solubility of the dyestuffs, can be used independently from one another or preferably in combination with one another.
• water-soluble compounds which have practically no influence on the solubility of the dyestuff, as extenders, anti-dusting agents or as anti-foaming agents.
• the preparations of the invention are much better soluble in water or in aqueous dyeing liquors, padding liquors or printing pastes and are, therefore, suitable for dyeing and printing synthetic and natural polyamide fibre materials, such as for example wool, silk or leather, whereby also in deep shades even, intense blue dyeings or prints free from dots are obtained.
• a good solubility is the first condition for their use, since rather a large amount of dyestuff, i.e. up to 70 parts of dyestuff in 1000 parts of a printing paste has to be incorporated into the relatively small volume of the printing paste besides the thickener and other reactants.
• the dyestuff preparations of the invention are also suitable for printing and dyeing the mentioned polyamide fibre materials in deep shades, since the dyestuffs having the structure usual during the preparation process, cause considerable difficulties for dissolution during dyeing and printing in the case of shades of medium intensity.
• polyglycols and polyglycol ethers of fatty alcohols or fatty acid amides containing hydroxyl groups which serve to increase the solubility of the dyestuffs
• the following substances may be mentioned for example: coconut oil alcohol polyglycol ether, stearyl alcohol polyglycol ether, oleyl alcohol-polyglycol ether, or oxethylated coconut oil acid monoethanol amide, to each of which 25 mols of ethylene oxide per mol of fatty alcohol or fatty acid amide are added.
• auxiliaries already mentioned above and used for the same purpose are for example dodecyl-benzene-phenyl ether disulfonate, dibutyl-naphthalene-sulfonate, oleic acid methyl tauride and oleic acid isethionate.
• non-ionic extenders such as dextrine, cane sugar or urea, which have practically no influence or only a slight influence on solubility, may be present.
• defoaming agent may be added for example tri-n-butyl phosphate and as dust-binding agent for example a mineral oil emulsion.
• the dyestuff and the additives may be finely ground in a mixing drum and in the usual dry crushing devices, as for example in a ball mill or pinned disc mill.
• Another possibility consists in spraying low-melting additives in a molten state onto the finely ground powder.
• the additives may also be added to the moist filter good obtained in usual way, of the organic dyestuff, or, if desired, to the aqueous dyestuff solution, from which dyestuff powder may be obtained by spray drying or dr drying.
• the parts indicated in the following Examples are by weight. If the dyestuffs are used with a content of pure colors below 100%, for example 95%, the residual content generally consists of alkali metal halides or alkali metal sulfonates resulting from the manufacturing process.
• the solubility of the dyestuff preparation in boiling water was 100 g/l, whereas the solubility of the dyestuff having a content of pure color of 95% (manufactured good) was only 40 g/l, calculated on a comparable color strength.
• this dyestuff preparation 55 Parts of this dyestuff preparation were introduced into 1000 parts of boiling water. After stirring for ten minutes the solution was filtered. The solution of the dyestuff preparation did not leave any ponderable residue on the filter.
• this dyestuff preparation 50 Parts of this dyestuff preparation were introduced into 1000 parts of boiling water. After stirring for ten minutes the solution was filtered. The solution of the dyestuff preparation did not leave any ponderable residue on the filter. If instead of 30 parts of polyglycol having the average molecular weight of 3000, 30 parts of polyglycol having the average molecular weight of 20.000 were used, a dyestuff preparation was obtained which had the same properties with regard to solubility.
